Do you know how spring rate works. 500 x 3, for every inch it takes 500 pounds. So for 3 inches 1500 pounds. 1000 pounds for 2 and 500 for one. That's not progressive.

Someone already explained it. Spring rate is the amount of force it takes to compress the spring 1 inch. For a 400 pound spring it would be 400 pounds for the first inch, 800 pounds for the second inch and 1200 pounds for the third inch. Does that make sense to you? You are burying yourself here.
For a spring it has to do with how the material reactes to the shear and bending.If you exceed these then it will be dammaged. Now you have to choose materials that meet the properties that we are looking at not out of the scope of the discussion
Ti deals with these forces better thats why they dont need as many coil hence the lighter weight.
